Microtensile Testing of Wood – Overview of Practical Aspects of Methodology

Microtensile testing is a specific and delicate variant of standard tensile testing and is performed on small samples. Often also referred to as “thin strip” method, the testing of thin veneers is described in this paper with particular aspects of its field and scope of application, along with comme...
